Question

A substance has a mass of 50g and a volume of 2mL. What is the density?

What is the formula you will use?
What is the answer?

Answer 1

`\boxed {\boxed {\sf d= 25 \ g/mL}}`

Step-by-step explanation:

Density is equal to mass over volume.

`\rho=(m)/(v)`

This is the formula used.

The mass is 50 grams and the volume is 2 milliliters.

`m= 50 \ g \\v= 2 \ mL`

Substitute the values into the formula.

`\rho =(50 \ g )/(2 \ mL)`

Divide.

`\rho= 25 \ g/mL`

The formula used is ρ=m/v and density is 25 grams per milliliter.
